1 Samuel 23:15-18

Now David became aware that Saul had come out to seek his life. David was in the Wilderness of Ziph [in the woods] at Horesh. And Jonathan, Saul’s son, arose and went [into the woods] to David at Horesh, and encouraged him in God. He said to him, “Do not be afraid; the hand of my father Saul will not find you. You will be king over Israel and I will be second in command to you; my father Saul knows this too.” So the two of them made a covenant before the LORD; and David stayed [in the woods] at Horesh and Jonathan went to his house.
